Going to put some old stuff on eBay and can't remember the manufacturer or intended purpose of these chassis. Appreciate any help. First one is steel with outer wire rails, second is a Camen but what class, third is a Zap again don't know what class.

Appreciate the info guys, but I'm thinking there not worth to much as none are currently available and probably not legal for any sanctioned racing. I think we where going to try the Slick 7 frame for spray glue 27s years ago but never did, looks like I even put ball bearings in the pillow blocks but never finished it.
